    Detecting Dynamic Resizing of a window in real time

    Is there some kind of a window listener with a method that can return the size of a jframe constantly during runtime so if a resize happens you can manipulate other things in the program accordingly. I have a simple program with circles bouncing around and i want to make it so if i resize the jframe (while viewing it with jcreators applet viewer) that i can resize the boundaries of where the circles can bounce to. - Sorry if thats confusing.

    Thanks -

    yes there is. you will have to add a componentlistener to your frame:


    Code:
    frame.addComponentListener(
    	new ComponentListener(){
    		public void componentResized(ComponentEvent e){
    			System.out.println("*FRAME: component resized");
    			Dimension size = frame.getSize();
    			doSomething();
    		}
    				
    		public void componentMoved(ComponentEvent e) {
    			System.out.println("*FRAME: component moved");
    			Point location = frame.getLocation();
    		}
    
    		public void componentHidden(ComponentEvent e) {}
    		public void componentShown(ComponentEvent e) {}
    	}
    );
    this will enable you to trace: resizing, moving, hiding and showing of your frame.
